Medical tests show that Little Wings has been exposed to radioactivity and may lose a leg unless it can be treated properly. Diet Smith and Tracy appeal to Professor Von Nucleus, a specialist in treating radiation poisoning.

Diet Smith brings Professor von Nucleus to the United States to cure Little Wings of her radiation poisoning. Against the rules of the hospital, von Nucleus locks himself in the room with Little Wings and begins his treatment. He cures her of her poisoning and quietly leaves the hospital and returns home. Odds Zonn, who has the same poisoning, goes to the hospital and demands that they give him the professor's machine so he can cure himself.
